What causes vacuum-sealed frozen fish fillets to sometimes become "loose" inside the packaging?

I often buy frozen bags of wild caught Alaskan Salmon, and each individual salmon fillet will come tightly vacuum sealed in a plastic bag of its own within the larger bag, basically keeping each one as fresh as possible. Recently I've noticed the occasional vacuum seal seems to not be sealed, and has air inside. Here's a video to show you what I mean. The fillet is moving around freely inside the package, basically defeating the entire point: https://imgur.com/a/Fk9KJue The full bag i bought at Wegmans last week had three like this. I'm just wondering if anyone knows what causes this to happen and whether they are still okay to eat? I'm assuming it would just lose its freshness/flavor a little faster, right? Or would the exposure to the air pocket inside the vacuum seal increase the chance of it turning bad? Thanks! submitted by /u/paulrudder [link] [comments]
